摘　　要：分别用60Co-γ射线、NaN3和航天诱变以不同剂量处理普那菊苣种子,对诱变处理后的植株进行了各项形态指标的测定。结果表明:普那菊苣对60Co-γ射线、NaN3和航天诱变的刺激在形态特性上显示出不同程度的应激效应;辐射诱变中高剂量处理对菊苣生长起到了明显的抑制作用;化学诱变各不同剂量处理对菊苣的影响不大;而航天诱变材料的综合表现最好。The seeds of Cichorium intybus.cv.Puna were irradiated by γ -ray , chemical by NaN3 and were spaced at different dose. The seedlings were measured by physiological and biochemical characteristics. The results indicated that ^60Co- γ ray, NaN3 and space mutagenesis made Puna chicory seedlings showing different degrees of stimulation effects on physiological and biochemical characteristics. High doses of radiation had played a significant inhibition on the growth of chicory; Chemical mutagenesis with various doses had little impact on chicory; Space mutagenesis materials had the best overall performance.
